I will start the process of face drawing with (full-faced) and then, we will work on profile and two third .

Concentration on seeing well

Before doing anything, we should learn to see well. That is, drawing requires seeing well. This theory is accompanied with the famous quote of Descartes: “I think, therefore I am” and is considered as criteria to enter the post-classic art which caused emerging of modernity attitude gradually. In short, how to see an object is a determinative fact in art.

How to copy?

Practicing on seeing well cause beautiful drawing. So before copying from this course, I recommend you to see it completely and keep what I explain in mind. Then, based on what you learned and what you experienced start drawing without looking at the course. For example, for those who are beginner, I recommend to divide each section more and then practice on each divided part.

Mental Practice

This action helps you get all necessary points which is generally called revelation too. In fact, our goal is just recognizing and identifying all the aspects and dimension which result in discovering new shapes.

First section: Integrated shape

We see the parts of face and head as an inverse egg which after seeing the distance of parts from each other, we do one forth division. This results in the identification of different of the face.  . As you will see in this course, geometrical view of head is the distance between two eyes. This is considered as measurement criteria and then we can specify other parts of face.

Second section: line fixing

After making sure from the right position of parts, we should draw the lines with darker colors specially perimeter line of head and nostril, ear cavity, cheek and cavity beside the eye tears        . 

Third section: Paying attention to the character

Be careful that another factor of similarity after considering physical principles of face (anatomy) is drawing and coloring the color of skin and line combination with colors. This action, embellish our drawing. In this section we will see that there is a general color in our drawing such as lips, eyes and hair. Also, as the background color is very light, we color it using the same color of parts of parts. 

Fourth section: anatomy

In this section we will implement the anatomy using brush which has broader coloring scale and has elimination effect. Then for architectural design size of tangible indents and ridges of face. In doing so, use bigger and wider bushes like old brush, gisinski ink as well as brush pen. For hair coloring also we use   burnt tree which all of them are available in brush library.
